The lipstick (5) is provided in the inner side of the fixing cup (1), and a longitudinal groove (21) is provided in the tube wall of the middle convolute tube (2). The fixing cup (1) comprises a cup wall (11) and a chassis (12). A vertical groove (112) is provided in the cup wall (11). The first lifting point (111) is provided under the vertical groove (112). The first lifting point (111) passes through the longitudinal groove (21) of the middle convolute tube (2) and is embedded in the internal thread (311,321) of the outer helix tube (3). The second lifting point (121) is provided on the external surface of the chassis (12).The second lifting point (121) passes through the vertical groove (112) and the longitudinal groove (21) and is embedded in the internal thread (311,321). The outer helix tube (3) is divided into an upper section and a lower section. The internal thread (321) of the lower section (32) has a width enough for the parallel movement of the first lifting point (111) and the second lifting point (121), while the internal thread (321) of the upper section (31) has a width only enough for the individual movement of the second lifting point (121).</p> |
